youtube is not working

when i opted for inspect element....this is what i got.....
Opera has modified script or content on www.youtube.com (PATCH-1164, YouTube force Flash player for HTML5 content). See browser.js for details

its not working mozila as well.... but it works in chrome..
everything in my pc is up to date... java...flash player...opera..
re installed opera.....but its not working for the last 3 days....

Go to the Adobe flash website in the Opera browser and download the latest version from there. It could be that you din't have the latest version working in Opera. Of course make sure you don't have turbo mode activated in the Opera browser. See if that helps.
